BASTL InstrumentsSPA GrandPa Expander (Aluminum)

Bastl SPA

SPA opens up a whole new level of functionality for Bastl's GrandPa grandular sampler module. It implements CV inputs for all crucial parameters and provides a dedicated clock input for influencing grain shifts. Every input features a dedicated attenuator and requires positive CV for proper functioning.

SPA Features

• Independent CV inputs for most parameters of the grandPa module
• CV inputs with attenuators are normalised to 5V so the attenuators work as direct controls of the parameters for both channels A and B of the grandPa
• CV inputs react only to positive voltages from 0-12V
• Grain Size and Shift Speed CV inputs with attenuators
• Switch to select whether the other two CV inputs with attenuators control Start / End  or Attack / Release parameters
• Crush cv input
• Grain Sync input to trigger grain shift
